Hi everyone. Recently I have returned to my old time hobby of HO scale train models and layouts. I need tunnel portals for my new layout and could not find one, that suits my needs. So I have created my own version.
Portal walls are covered by large natural stones. with concrete beam on top. This is a single track version.
It's sized to be used with track with a ballast prism, like Roco Geoline. There is enough hight to let loco with an open pantograph to pass through.
!!!Please note!!! that concrete beam is sticking out from the wall on 2 mm. My printer handled this well. Just few loose strings, which I cut and the rest loos good. If you are not sure, use custom support.
I will be adding more files soon: Double track portal, portal with side walls and pillars.
Enjoy!
